一般标量平衡律的稳定性和全变差估计

Stability and Total Variation Estimates on General Scalar Balance Laws

Rinaldo M. Colombo, Magali Mercier, Massimiliano D Rosini

摘要:

考虑几个空间维度中的一般标量平衡定律$\partial_t u + \Div f(t, x,u) = F(t,x,u)$。本文的目的是估计其解与流$f$和源$F$的依赖关系。为此,得到了解的空间变量的全变差的界。这个结果然后被应用到获得适定性和稳定性估计的平衡律与非局部源。

英文摘要:

Consider the general scalar balance law $\partial_t u + \Div f(t, x,u) = F(t,x,u)$ in several space dimensions. The aim of this note is to estimate the dependence of its solutions from the flow $f$ and from the source $F$. To this aim, a bound on the total variation in the space variables of the solution is obtained. This result is then applied to obtain well posedness and stability estimates for a balance law with a non local source.
